Yeah, don't question motives. Go be a good capitalist.
What money? There's no platform for payments or advertising on Telegram. Advertising doesn't seem very practical with bots. Telegram has given no details or examples of what qualifies for the $25k rewards. It's not clear what level of production they're looking for... a bot that tells you the weather or a virtual girlfiend with full-blown NLP? Innovation prizes are cool but you can't play if you don't remotely know what qualifies as winning.
